Hello All,

The IP Office is a VOIP System and has a lot of applications. So you need to be an expert of networking and operating system. I will use this thread to create a list of the best DOS commands or Freeware Applications.
Everyone had once the feeling: “That is an ingenious assistance!”
Please tell use your experience!
What do you think is a great help to make a good service at the IP Office?

e.g.:
DOS Command:
IP Port Conflict at a Server:
"netstat -a -o" in a DOS box tells you which ports are in use on a server and also which application Process ID uses the open port / ports.

The arp -a command tells you ip address and physical address of devices on your network.

"The lack of understanding is the root of all problems

Need to quick test if a network is Diffserve enabled?
A ping does not give a proper result as these packets are not marked for QoS.
On Windows 2000/XP/Server 2003 you can use a option with Ping : -v TOS.
With this option you can ping with the Diffserve TOS bits set, but first you have to enable this feature in the registry:
1. Start Registry Editor (Regedt32.exe).
2. Go to the following key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TcpIp\Parameters
3. If you are running Windows 2000, follow these steps:
a. On the Edit menu, click Add Value.
b. In the Value name box, type DisableUserTOSSetting.
c. In the Data Type list, click REG_DWORD, and then click OK.
d. In the Data box, type a value of 0 (zero), and then click OK.
If you are running Windows XP or Windows Server 2003, follow these steps:
a. On the Edit menu, point to New, and then click DWORD Value.
b. Type DisableUserTOSSetting as the entry name, and then press ENTER. When you add this entry, the value is set to 0 (zero). Do not change the value.

4. Quit Registry Editor, and then restart the computer.

Now you can ping with or without the TOS bits set and compare the results, Ping with TOS should give lower loopback times.
Open a DOS box and enter "ping -t -v 139 192.168.42.1

I found out if you run a Tftp-server on VM-Pro and you reboot the VM-Server 3.2(28) then the IP_O will also reset.


Also if you do a tracert (IP-Adres) then you can see the hops and see the route it take,s.

Good to see when you are using VPN tunneling.
